Network Administration: DHCP Snooping and DHCP Relay

FILE LOCATION:  C:\Users\gina\Desktop\Checkout_new\Dell Astute\User 

Guide\Dell_Astute_Network_Admin_DHCP_Snooping&Relay.fm

D E L L   C O N F ID E N T IA L   –   P R E L IM I N A R Y   8 / 9 /1 6   -   FO R  PR O O F   O N L Y

DHCP snooping filters untrusted messages, and stores these messages in a 

database. Interfaces are untrusted if the packet is received from an interface 

outside the network, or from an interface beyond the network firewall. 

Trusted interfaces receive packets only from within the network or the 

network firewall. 
The DHCP Snooping Binding database contains the untrusted interfaces’ 

MAC address, IP address, Lease Time, VLAN ID, and interface information. 
Table 18-1 describes how DHCP packets are handled when DHCP snooping 

is enabled on an interface.

Table 18-1. DHCP Packet Handling when DHCP Snooping is Enabled

Packet Type

Forward the packet 

according to DHCP 

information. If the

unknown the packet is 

filtered.

DHCPREQUEST
